Answer:

Step-by-step explanation:

Since, Sum of triangle is equal to 180°

180 = 2x + 50 + 3x - 10

180 = 5x + 40

180 - 40 = 5x

140 = 5x

140/5 = x

28 = x

Answer:

50+2x+(3x-10)=180

From there we do prealgebra

then x=28

Give two systems of equations that would be easier to solve by substitution than by elimination. Then give two systems that would be easier to solve with elimination. Finally, explain how you decide whether to use elimination or substitution to solve a system.

Answers

Answer:

Answer: These techniques for elimination are preferred for 3rd order systems and higher. They use "Row-Reduction" techniques/pivoting and many subtle math tricks to reduce a matrix to either a solvable form or perhaps provide an inverse of a matrix (A-1)of linear equation AX=b. Solving systems of linear equations (n>2) by elimination is a topic unto itself and is the preferred method. As the system of equations increases, the "condition" of a matrix becomes extremely important. Some of this may sound completely alien to you. Don't worry about these topics until Linear Algebra when systems of linear equations (Rank 'n') become larger than 2.

The formula for the surface area of the bottom cushion is

A = 2wl + 2lh + 2hw (w is width, l is length, h is height)

w = 18, l = 21, h = 3

A = 2(18)(21) + 2(21)(3) + 2(3)(18)

A = 2(378) + 2(63) + 2(54)

A = 756 + 126 + 108

Four graphs are shown below:

Scatter plot A is shown with data points that move in an upward direction and are located at 1 and 0.3, 2 and 1, 3 and 2, 4.1 and 4, 5.2 and 6.1, 5.9 and 9.5. Additional points are located at 4.6 and 5, 5.8 and 7.4, 5.2 and 7.1. Scatter plot B shown with data points that move in an upward direction and are located at 0 and 2, 1 and 3, 2 and 4, 3 and 5, 4 and 6, 5 and 7, 6, and 8, 7 and 9. Scatter plot C shown with data points that move in a downward direction and are located at 0.1 and 8.7, 4 and 5.6, 5 and 4.3, and 6 and 0.5. Additional points are located at 5.9 and 1.5, 5.5 and 3.5. Scatter plot D is shown with points that move in a downward direction and are located at 0 and 7, 1 and 6, 2, and 5, 3 and 4, 4 and 3, 5 and 2, 6, and 1.

Which graph represents a positive linear association between x and y?

Graph A
Graph B
Graph C
Graph D

Answers

Answer:

Step-by-step explanation: im pretty sure its a

The required graph B shows the data points that move upward direction and are located at 0 and 2, 1 and 3, 2 and 4, 3 and 5, 4 and 6, 5 and 7, 6, and 8, 7 and 9. Option B is correct.

Graphs have been shown below, the graph with the positive linear association between x and y to be determined.

What is a graph?

The graph is a demonstration of curves that gives the relationship between x and y-axis.

Options C and D can be omitted first because question asked for positive linear association between x and y, but in both graphs have negative associations so both options are incorrect.
While Option A and B have a positive association but graph A does not have a linear association so graph A will also be omitted. Graph B has a linear association because a straight curve represents linearity.

Thus, the required graph B shows the data points that move upward direction and are located at 0 and 2, 1 and 3, 2 and 4, 3 and 5, 4 and 6, 5 and 7, 6, and 8, 7 and 9. Option B is correct.

Please help on my surface area ;-; <3 good luck I will give brainiest to the correct one

Answers

Answer: 207

Step-by-step explanation:

To find the surface area, find the area of all the shapes in the three-dimensional figure and then add them.

Find the area of the two triangles first:

1/2*b*h = area of a triangle

1/2* 8* 9= 36

36 is the area of one of the triangles.

Multiply 36 by two because there are two triangles.

=72

Then find the area of the squares/rectangles.

8*5= 40

9*5= 45

10*5 = 50

72+40+45+50

=207

How many solutions does the system have? y=−2x−4 y=3x+3

Answers

Answer:

One Solution

Step-by-step explanation:

First substitute the y in the first equation with the second equation to get

-2x-4=3x+3

since theres a variable of both sides, you subtract the variable with the least coefficient, in this case, you add 2x to both sides to get

-4=5x+3

subtract the constant on both sides to get

-1=5x

divide both sides by 5

x= -0.2 or -1/5

One solution, I’m sorry if this is wrong but I remember studying this so I’m hope I’m right!
